WebNumerous template-free methods exist for the production of mesoporous structures, but they are often experimentally complicated or the obtained pores are heterogeneous.11These problems can be overcome by using template methods, where a mold is used to cast a matrix material and later removed. WebIn this work, we prepared highly swelling, stimuli-responsive hydrogels capable of the highly efficient adsorption of inorganic pollutants. The hydrogels were based on hydroxypropyl methyl cellulose (HPMC) grafted with acrylamide (AM) and 3-sulfopropyl acrylate (SPA) and were synthesized via the growth (radical polymerization) of the grafted copolymer chains …
